This publication has five parts, plus
appendixes. "Part 1. Planning for System Generation"
describes the components, features, and
options of VM/370, and tells you what you
must do during system generation to support
them. Part 1 includes information about CMS, RSCS, and other operating systems in a
virtual machine. It also discusses
performance options, remote 3270s, the 3704/3705 control program, saved systems,
discontiguous saved segments, CMS/DOS, VSAM under CMS, Access Method Services, the
Attached Processor System, storage

Page of GC20-1801-10 As Updated April 1, 1981 by TNL GN25-0837 • The term "3705" refers to the IBM 3705-1
and 3705-11 Communications Controllers, unless otherwise specified. • The term "3270" is used in this
publication to refer to all VM/370 supported virtual machine display
consoles unless otherwise noted. A
specific device type is used only when a
distinction is required between device
types. • Information about display terminal usage
also applies to the IBM 3138, 3148 and
3158 Display Consoles, when used in
display mode, unless otherwise noted. • Any information pertaining to the IBM
3284 or 3286 printer also pertains to 3287, 3288, 3289 unless otherwise noted. • The term "typewriter terminal" refers to
printer-keyboard devices that produce
hard-copy output only (such as the IBM
2741 Communication Terminal, the IBM
3215 Console printer-Keyboard, or the IBM 3767 Communication Terminal, Model 1
or 2, operatinq as a 2741). • The term "2741" refers to the
Communication Terminal, and
3767 Communication Terminal
otherwise noted).

(unless • The term "display device" refers to any VM/370 supported system console terminal
that displays data on a screen. • Unless otherwise noted, where the term
"Attention key" is used in this
publication, the phrase "(or equivalent)" is implied. Th€ equivalent
key on the 1050 terminal is the RESET LINE key; on the 3276, 3277, and 3278
terminal, the Enter key. Each of the
terminals that can be used with the system has a key that is the
equivalent of the Attention key on the
2741 (with which you can signal an
attention interrupt). • CMS/DOS is part of the CMS system and is
not a separate system. The term "CMS/DOS" is used in this publication as
a concise way of stating that the DOS simulation mode of CMS is currently
active; that is, that the CMS command
set dos on
has been previously invoked. • The phrase "the CMS file system" refers
to disk files that are in CMS's 800-byte, 1K, 2K, or 4K fixed physical
block format; CMS's VSAM data sets are
not included. • Unless stated otherwise, reference to
the System/370 Models 138 and 148 also
apply to Models 135-3 and 145-3,
respectively. • The term "3330V" is used in this
publication for both volumes and device
addresses. When used with volumes, it
refers to a Mass Storage System volume
that has been mounted and that is
directly accessible from the processor.
When used with device addresses, 3330V refers to a device on which 3330V volumes may be mounted by the Mass Storage System. 'hen an installation installed and an IBM 3850 Mass Storage System attached to the processor,
references to 3330 can be thought of as meaning 3330Vs unless the reference is to VM/370 system residence, paginq or
spooling devices. COREQUISITE PUBLICATIONS Order No. GC20-1808 User's GC20-1810 Order No. in Order No. GC20-1821 Con!£Q! Order No. Order No. GC20-1834 l11Q Q§§ign, Order No. GA27-2749. iv IBM VM370 Planning and System Generation Guide
